Description

[Technical Field]

[0001] The present invention relates to a muffler cover. [Background technology]

[0002] Conventionally, mufflers for saddle-ride type vehicles have been known in which the muffler body is covered with a muffler cover to prevent the occupant's legs from touching the hot muffler body (see, for example, Patent Document 1). In the muffler described in Patent Document 1, the front half of the muffler body is covered with a front muffler cover, and the rear half of the muffler body is covered with a rear muffler cover to protect the muffler body. The rear muffler cover tapers rearward, and an opening is formed in the rear surface of the rear muffler cover. A tailpipe protruding rearward from the muffler body is exposed rearward through the opening in the rear muffler cover. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-162093 Summary of the Invention [Problem to be solved by the invention]

[0004] However, if openings are provided on the sides of the rear muffler cover to change the design or to allow for heat dissipation, the inside of the muffler cover is exposed to the outside, which causes a problem of poor appearance.

[0005] The present invention has been made in consideration of the above points, and has an object to provide a muffler cover that can improve heat dissipation performance while preventing deterioration of the appearance of the muffler. [Means for solving the problem]

[0006] One aspect of the present invention is a muffler cover for a muffler with a tail pipe protruding rearward, and comprises a tail cover that surrounds the rear end of the tail pipe, a side cover that covers the tail pipe from the side, and a plate installed inside the side cover, with the plate positioned with a gap between the tail pipe and the side cover, and an opening formed in the side cover, so that the plate overlaps the opening in the side cover when viewed from the side, thereby solving the above-mentioned problem. [Effects of the Invention]

[0007] According to the muffler cover of one aspect of the present invention, even if an opening is formed in the side cover, the plate prevents the inside of the muffler cover from being exposed, so the appearance of the vehicle is not impaired. Because there is a gap between the plate and the side cover, hot air from the tailpipe is discharged to the outside through the opening in the side cover, reducing heat damage to the covers. The plate prevents hot air from the tailpipe from being discharged directly through the opening in the side cover, reducing heat damage to the outside. [Brief explanation of the drawings]

[0009] A tailpipe protrudes rearward from a muffler according to one embodiment of the present invention. The muffler cover of this muffler has a tail cover that surrounds the rear end of the tailpipe and a side cover that covers the tailpipe from the sides. A plate is installed inside the side cover, and the plate is positioned with a gap between the tail cover and the side cover. An opening is formed in the side cover, and the plate overlaps the opening in the side cover in a side view. The plate prevents the inside of the muffler cover from being exposed, thereby not impairing the vehicle's appearance. Because there is a gap between the plate and the side cover, hot air from the tailpipe is discharged to the outside through the opening in the side cover, thereby reducing heat damage to the covers. The plate prevents hot air from the tailpipe from being directly discharged through the opening in the side cover, thereby reducing heat damage to the outside. [Example]

[0010] A saddle-ride type vehicle equipped with a muffler cover of this embodiment will be described below with reference to the accompanying drawings. Fig. 1 is a right side view of the saddle-ride type vehicle of this embodiment. In the following drawings, arrow Fr indicates the front of the vehicle, arrow Re indicates the rear of the vehicle, arrow L indicates the left side of the vehicle, and arrow R indicates the right side of the vehicle.

[0011] As shown in Fig. 1, a saddle-type vehicle 1 is configured by mounting an engine 31, an electrical system, and other various components on a body frame 10 formed of pipes and sheet metal. The body frame 10 has a pair of main frames 12 that branch off to the left and right from a head pipe 11 and extend rearward, and a pair of down frames 13 that branch off to the left and right from the head pipe 11 and extend downward. The pair of main frames 12 support the rear of the engine 31, and the pair of down frames 13 support the front of the engine 31. Supporting the engine 31 on the body frame 10 ensures the rigidity of the entire vehicle.

[0012] The front portion of the main frame 12 forms a tank rail (not shown) located above the engine 31, and a fuel tank 21 is supported from below by the tank rail 14. The rear portion of the main frame 12 forms a body frame 15 located behind the engine 31, and a swing arm 22 is swingably supported on the lower half of the body frame 15. An upper rail 16 extends rearward from the top of the body frame 15, and a lower rail 17 extends diagonally upward and rearward from a middle position of the body frame 15 in the vertical direction. A seat 23 is supported from below by the upper rail 16 and the lower rail 17.

[0013] A pair of front forks 24 are steerably supported on the head pipe 11 via a steering shaft (not shown). A front wheel 25 is rotatably supported on the lower part of the front forks 24, and an upper part of the front wheel 25 is covered by a front fender (not shown). A swing arm 22 extends rearward from the body frame 15. A rear wheel 26 is rotatably supported on the rear end of the swing arm 22, and an upper part of the rear wheel 26 is covered by a rear fender (not shown). An engine 31 is connected to the rear wheel 26 via a chain drive type transmission mechanism, and power from the engine 31 is transmitted to the rear wheel 26 via the transmission mechanism.

[0014] The engine 31 is a four-stroke single-cylinder engine that is suspended inside the body frame 10 via multiple suspension brackets. A cylinder assembly, which is made up of a stacked cylinder 33, a cylinder head 34, and a cylinder head cover 35, is attached to the top of the crankcase 32 of the engine 31. An exhaust pipe 36 is connected to the front of the cylinder head 34. The exhaust pipe 36 passes below the crankcase 32 and extends rearward, and a chamber-type muffler 41 is connected to the downstream end of the exhaust pipe 36 via a catalyst case 37. A tailpipe 43 protrudes from the rear of the muffler 41.

[0015] High-temperature exhaust gas is discharged from the tailpipe 43, causing the tailpipe 43 itself to become hot. The tailpipe 43 is covered by the muffler cover 50 to prevent the rider's legs from touching the tailpipe 43. However, if openings are formed on the sides of the muffler cover 50 for design changes or heat dissipation, the inside of the muffler cover 50 will be exposed through the openings, degrading the appearance. Therefore, in the muffler cover 50 of this embodiment, a plate 81 (see Figure 6) is installed so that it overlaps the openings of the muffler cover 50 from the inside and leaves a gap between it and the muffler cover 50, thereby ensuring heat dissipation while minimizing exposure of the inside of the muffler cover 50.

[0016] The muffler will be described with reference to Figures 2 to 6. Figure 2 is a right side view of the muffler of this embodiment. Figure 3 is a rear view of the muffler of this embodiment. Figure 4 is a perspective view of the tail cover of this embodiment. Figure 5 is a perspective view of the side cover of this embodiment. Figure 6 is a side view of the muffler cover of this embodiment.

[0017] As shown in Figures 2 and 3, exhaust gas from the engine 31 (see Figure 1) is sent to the muffler 41 through the exhaust pipe 36 and catalyst case 37. A catalyst is housed inside the catalyst case 37, and the catalyst purifies air pollutants contained in the exhaust gas, such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx). A first exhaust gas sensor 38 is attached to the exhaust pipe 36 upstream of the catalyst, and a second exhaust gas sensor 39 is attached to the catalyst case 37 downstream of the catalyst. The detection results of the first and second exhaust gas sensors 38, 39 are used for diagnosing catalyst deterioration, etc.

[0018] The muffler 41 is formed into a generally rectangular box shape in top view by an upper case and a lower case. An expansion chamber is formed inside the muffler 41, and as exhaust gas flows from the catalyst case 37 into the muffler 41, the exhaust gas expands in the expansion chamber within the muffler 41, reducing exhaust noise. Support brackets 42 (only the right side is shown) are provided on both side walls of the muffler 41, and the muffler 41 is supported from above by the body frame 15 (see FIG. 1) via the support brackets 42. A tailpipe 43 protrudes from the rear right side of the muffler 41, and exhaust gas is discharged to the outside from the rear end of the tailpipe 43.

[0019] A muffler cover 50 is attached to the rear of the muffler 41, and the tail pipe 43 is covered by the muffler cover 50 to prevent the legs of occupants from coming into contact with the high-temperature tail pipe 43. The rear end of the tail pipe 43 is enclosed by a tail cover 51 at the rear of the muffler cover 50, and the tail pipe 43 is covered from the side by a side cover 71 on the right side of the muffler cover 50. Two openings 72 and 73 are formed in the side cover 71. A plate 81 is attached to the inside of the side cover 71, and the plate 81 covers the two openings 72 and 73 of the side cover 71 from the inside, thereby reducing exposure of the inside of the side cover 71.

[0020] As shown in Figure 4, the tail cover 51 is made of stainless steel and is formed by connecting a frame-shaped rear wall 52 and a semi-cylindrical side wall 53. A circular opening 54 is formed in the rear wall 52 of the tail cover 51, and the rear end of the tail pipe 43 (see Figure 2) is positioned inside the opening 54 in the rear wall 52. A side wall 53 projects from the left outer edge of the rear wall 52 of the tail cover 51, and covers the left side of the tail pipe 43. A backing plate 55 is fixed to the inner surface of the side wall 53 of the tail cover 51, and an insertion port 56 is formed by the side wall 53 and the backing plate 55. An insertion piece (not shown) of the muffler 41 (see Figure 2) is inserted into the insertion port 56.

[0021] An upper bracket 61 is welded to the upper inner surface of the side wall 53 of the tail cover 51, and a lower bracket 62 is welded to the lower inner surface of the side wall 53 of the tail cover 51. The fixing surfaces of the upper bracket 61 and the lower bracket 62 face to the right, and through holes 63, 64 are formed in the fixing surfaces of the upper bracket 61 and the lower bracket 62. A plate 81 and a side cover 71 are fixed to the upper bracket 61 and the lower bracket 62. A cushioned insertion piece 57 is fixed to the upper outer surface of the side wall 53 of the tail cover 51, and the insertion piece 57 is inserted into an insertion port (not shown) formed by the receiving plate 44 of the muffler 41 and the side cover 71.

[0022] As shown in Figure 5, side cover 71 is made of stainless steel and formed into a semi-cylindrical shape. Side cover 71 covers the rear of muffler 41 and the right side of tailpipe 43, with the rear side of side cover 71 overlapping tail cover 51 in a side view. Two openings 72, 73 are formed in the side of side cover 71, lined up front and rear. Openings 72, 73 are each formed vertically long, and are positioned to the sides of tailpipe 43 (see Figure 2) inside muffler 41. The vertically long openings 72, 73 improve the appearance of muffler 41, and also allow hot air around tailpipe 43 to be exhausted to the outside through openings 72, 73.

[0023] A fixing portion 74 bulges inward from the front of the side cover 71, and is screwed to the mounting plate 45 (see FIG. 2) on the right side of the muffler 41. An upper stay 75 is welded to the inner surface of the upper part of the side cover 71, and a lower stay 76 is welded to the inner surface of the lower part of the side cover 71. The fixing surfaces of the upper stay 75 and the lower stay 76 of the side cover 71 face leftward, and notched holes 77, 78 are formed in the fixing surfaces of the upper stay 75 and the lower stay 76. The rear ends of the notched holes 77, 78 are open, and the notched holes 77, 78 correspond to the through holes 63, 64 of the upper bracket 61 and the lower bracket 62 of the tail cover 51.

[0024] As shown in Fig. 6, the plate 81 is made of a steel plate with a heat-resistant black paint applied, and is formed separately from the side cover 71 and the tail cover 51. By forming the plate 81 from a material different from the side cover 71 and the tail cover 51, costs are reduced and the degree of freedom in the shape of each component is increased, improving the appearance of the vehicle. The plate 81 has a shielding portion 82 that overlaps with the openings 72, 73 on the side of the side cover 71 in a side view. The shielding portion 82 is installed with a gap between the tail pipe 43 (see Fig. 2) and the side cover 71, which reduces exposure inside the cover and allows hot air to be exhausted from the openings 72, 73.

[0025] An upper fixing portion 83 extends from the upper edge of the shielding portion 82, and a lower fixing portion 84 extends from the lower edge of the shielding portion 82, with the upper fixing portion 83 and the lower fixing portion 84 being fixed to the side cover 71 and the tail cover 51. Stud bolts 85, 86 are welded to the upper fixing portion 83 and the lower fixing portion 84, and the stud bolts 85, 86 protrude to the left side from the upper fixing portion 83 and the lower fixing portion 84. The plate 81 and the tail cover 51 are fastened together to the upper stay 75 and the lower stay 76 of the side cover 71 by the stud bolts 85, 86 and nuts 87, 88. Fastening the plate 81, tail cover 51, and side cover 71 together improves assembly ease.

[0026] The upper fixing portion 83 and the lower fixing portion 84 are bent, and the shielding portion 82 is closer to the openings 72, 73 of the side cover 71 than the upper fixing portion 83 and the lower fixing portion 84. By separating the shielding portion 82 from the upper fixing portion 83 and the lower fixing portion 84, the plate 81 can be easily fixed to fit the semi-cylindrical shape of the side cover 71, and the shape of the plate 81 does not impair the degree of freedom in the shape of the side cover 71. In addition, the gap between the shielding portion 82 of the plate 81 and the side cover 71 is easy to adjust, and by ensuring an appropriate gap while maintaining the appearance of the vehicle, the heat dissipation performance of the muffler cover 50 is not impaired by the shielding portion 82.

[0027] As shown in FIG. 3 , the upper fixing portion 83 and the lower fixing portion 84 (stud bolts 85, 86) of the plate 81 are located above and below the tail pipe 43 in a rear view. The upper fixing portion 83 and the lower fixing portion 84 overlap the tail pipe 43 in the vertical direction, so that the tail pipe 43 can be brought closer to the shielding portion 82, which is recessed relative to the upper fixing portion 83 and the lower fixing portion 84. By narrowing the gap between the shielding portion 82 and the tail pipe 43, the plate 81 and the side cover 71 can be installed compactly. In addition, the side cover 71 partially overlaps the upper and lower parts of the tail cover 51. The upper stay 75 and the lower stay 76, the upper bracket 61 and the lower bracket 62 are also located above and below the tail pipe 43.

[0028] 6, the vertical dimension of the plate 81 in a side view is larger than the outer diameter of the tail pipe 43 (see FIG. 2), and the area of ​​the plate 81 in a side view is larger than the combined area of ​​the openings 72, 73 of the side cover 71. The larger area of ​​the plate 81 makes it difficult to see the interior through the openings 72, 73 of the side cover 71. The plate 81 effectively blocks hot air from the tail pipe 43 toward the openings 72, 73 of the side cover 71, preventing the high-temperature hot air from being directly discharged to the outside through the openings 72, 73 of the side cover 71. This reduces heat damage not only to the side cover 71 but also to external peripheral components.

[0029] The assembling operation of the muffler cover will be described with reference to Figures 7 and 8. Figures 7 and 8 are explanatory diagrams of the assembling operation of the muffler cover of this embodiment.

[0030] 7(A) and (B), plate 81 is brought close to side cover 71 from the rear. In this case, the space between upper stay 75 and lower stay 76 and the inner side surface of side cover 71 is narrow. To allow plate 81 with stud bolts 85 and 86 to fit into this space, notched holes 77 and 78 are formed in upper stay 75 and lower stay 76 instead of through holes. Stud bolts 85 and 86 are passed through the open ends (rear ends) of notched holes 77 and 78 in upper stay 75 and lower stay 76, and stud bolts 85 and 86 of plate 81 are hooked onto upper stay 75 and lower stay 76.

[0031] As shown in Figure 8(A), the tail cover 51 is fixed to the side cover 71 and the plate 81. In this case, the tail cover 51 is brought closer to the side cover 71 from the side, and stud bolts 85, 86 are inserted into the through holes 63, 64 of the upper bracket 61 and the lower bracket 62 of the tail cover 51. The stud bolts 85, 86 protrude from the notched holes 77, 78 and the through holes 63, 64, and nuts 87, 88 are tightened onto the stud bolts 85, 86, fastening the side cover 71, plate 81, and tail cover 51 together. In this manner, the muffler cover 50 is assembled from the side cover 71, plate 81, and tail cover 51.

[0032] As shown in Figure 8(B), when fixing the muffler cover 50 to the muffler 41, the insertion pieces 57 (see Figure 8(A)) of the tail cover 51 are inserted into insertion holes (not shown) formed by the backing plate 44 of the muffler 41 and the side cover 71, and the insertion pieces (not shown) of the muffler 41 are inserted into insertion holes 56 (see Figure 4) formed by the side walls 53 and backing plate 55 of the tail cover 51. Then, the fixing portions 74 of the side covers 71 are screwed to the installation plates 45 (see Figure 2) of the muffler 41, and the tail pipe 43 is covered by the tail cover 51 and the side covers 71. A plate 81 is positioned between the openings 72, 73 of the side covers 71 and the tail pipe 43, reducing exposure of the tail pipe 43.

[0033] As described above, according to the muffler cover 50 of this embodiment, even if the openings 72, 73 are formed in the side cover 71, the plate 81 prevents the inside of the muffler cover 50 from being exposed, so the appearance of the vehicle is not impaired. Because there is a gap between the plate 81 and the side cover 71, hot air from the tail pipe 43 is discharged to the outside through the openings 72, 73 of the side cover 71, reducing heat damage to the covers. The plate 81 prevents hot air from the tail pipe 43 from being discharged directly through the openings 72, 73 of the side cover 71, reducing heat damage to the outside.

[0034] In this embodiment, the tail cover is formed by connecting a frame-shaped rear wall and a semi-cylindrical side wall, but the shape of the tail cover is not particularly limited as long as it is formed to surround the rear end of the tail pipe.

[0035] Furthermore, in this embodiment, the side covers are formed in a semi-cylindrical shape, but the shape of the side covers is not particularly limited as long as the side covers are formed so as to cover the tail pipe from the sides.

[0036] In addition, in this embodiment, the plate is formed to have a curved upper fixing portion and a lower fixing portion, but the shape of the plate is not particularly limited as long as the plate is formed to overlap the opening inside the side cover.

[0037] In addition, in this embodiment, two vertically elongated openings are formed in the side cover in a row, one in front and one in back, but the number, shape, and location of the openings are not particularly limited.

[0038] In addition, in this embodiment, the plate is installed so as to overlap the entire opening of the side cover in a side view, but the plate may be installed so as to overlap only part of the opening of the side cover in a side view.

[0039] In addition, in this embodiment, the tail cover, side cover, and plate are fastened together with stud bolts and nuts, but the method of fastening the tail cover, side cover, and plate is not particularly limited.

[0040] The muffler cover of this embodiment is not limited to the saddle-ride type vehicle described above, and may be used in other types of saddle-ride type vehicles. Note that the saddle-ride type vehicle is not limited to all vehicles in which the rider sits astride the seat, but also includes scooter-type vehicles in which the rider does not sit astride the seat.

[0041] As described above, the first aspect is a muffler cover (50) for a muffler (41) with a tailpipe (43) protruding rearward. The muffler cover (50) includes a tail cover (51) surrounding the rear end of the tailpipe, side covers (71) covering the tailpipe from the sides, and plates (81) attached to the inside of the side covers. The plates are positioned with a gap between the tailpipe and the side covers, and openings (72, 73) are formed in the side covers, with the plates overlapping the openings in the side covers in a side view. With this configuration, even if openings are formed in the side covers, the plates prevent the inside of the muffler cover from being exposed, thereby preventing the vehicle's appearance from being impaired. Because there is a gap between the plates and the side covers, hot air from the tailpipe is discharged to the outside through the openings in the side covers, thereby reducing heat damage to the covers. The plates prevent hot air from the tailpipe from being directly discharged through the openings in the side covers, thereby reducing heat damage to the outside.

[0042] In the second aspect, in the first aspect, the opening of the side cover is located to the side of the tail pipe. With this configuration, even if the opening of the side cover is formed to the side of the tail pipe, the plate blocks hot air from flowing from the tail pipe toward the opening of the side cover, and the hot air is not directly discharged to the outside through the opening of the side cover.

[0043] In a third aspect, in the first or second aspect, the vertical dimension of the plate is larger than the outer diameter of the tailpipe, and the area of ​​the plate in a side view is larger than the area of ​​the opening in the side cover. With this configuration, the plate makes it difficult to see the interior through the opening in the side cover. In addition, the plate effectively blocks hot air from the tailpipe toward the opening in the side cover, preventing high-temperature hot air from being directly discharged to the outside through the opening in the side cover.

[0044] In a fourth aspect, in any one of the first to third aspects, the plate has a shielding portion (82) that overlaps the opening of the side cover and fixing portions (upper fixing portion 83, lower fixing portion 84) that are fixed to the side cover, with the shielding portion being closer to the opening of the side cover than the fixing portions. With this configuration, the fixing portion and the shielding portion of the plate are spaced apart, making it easy to fix the plate to fit the shape of the side cover, and the shape of the plate does not impair the degree of freedom in the shape of the side cover. In addition, the gap between the shielding portion of the plate and the side cover is easy to adjust, and by ensuring an appropriate gap while maintaining the appearance of the vehicle, heat dissipation performance is not impaired by the shielding portion.

[0045] In a fifth aspect, in the fourth aspect, the fixing portions are located above and below the tail pipe in a rear view. With this configuration, the fixing portions of the plate overlap the tail pipe in the vertical direction, bringing the shielding portions of the plate closer to the tail pipe, and allowing the plate and side covers to be installed compactly.

[0046] In a sixth aspect, in any one of the first to fifth aspects, the side cover and the plate are formed separately, the side cover is provided with stays (upper stay 75, lower stay 76), and the plate and tail cover are fastened together to the stays of the side cover. With this configuration, the plate, tail cover, and side cover are fastened together, improving assembly. In addition, by using different materials for the side cover and the plate, costs can be reduced, and the degree of freedom in the shape of each component is increased, improving the appearance of the vehicle.

[0047] In the seventh aspect, in the sixth aspect, stud bolts (85, 86) are provided on the plate, and notched holes (77, 78) are formed in the stays of the side covers, with the stud bolts inserted into the notched holes and nuts (87, 88) tightened onto the stud bolts protruding from the notched holes, thereby fastening the side cover, plate, and tail cover together. With this configuration, even if the space between the side cover and the stay is narrow, the notched holes formed in the stays make it possible to insert the plate with the stud bolts between them. The stud bolts of the plate are passed through the open ends of the notched holes in the stays, allowing them to be hooked onto the stays. The side cover, plate, and tail cover can then be easily fastened together using the stud bolts and nuts.

[0048] Although the present embodiment has been described, other embodiments may be made by combining the above-described embodiments and modifications in whole or in part.

[0049] Furthermore, the technology of the present invention is not limited to the above-described embodiments, and various changes, substitutions, and modifications may be made without departing from the spirit of the technical idea. Furthermore, if the technical idea can be realized in a different way due to technological advances or other derived technologies, it may be implemented using that method. Therefore, the claims cover all embodiments that may fall within the scope of the technical idea. [Explanation of symbols]
